There have been numerous reports of the equinox coils breaking at the ears.
While I am a proud owner of this machine, I have not experienced this but have seen plenty of pictures of broken ears.
Many requests have come in wanting us to design a method of salvaging a coil that has succumbed to the broken ear syndrome. We are working on that. I hate patches though.
I would rather answer the question of why they break, and develop a solution so they don't break in the first place.
The bolts transfers all lateral forces into the ears.
1. The lower shaft is not resting on the coil longitudinally. (unsupported area in the above graphic).
2. The ears are not thick enough to offer resistance to bending and ultimately breaking.
So we developed this Doodad to fix those issues and eliminate ear breakage.
Its function is to double the ear thickness by adding external ear backup and eliminate the unsupported areas below the shaft.
